Heterogeneity Modeling and Low-Dimensional Broadcast Cooperative Control of Air Conditioning Load for Power Grid Demand Response
摘要
Abstract
To address the demand for refined regulation of large-scale heterogeneous air-conditioning loads in power grid demand response,a second-order equivalent thermal parameter model is firstly used to derive the steady-state operating power of air conditioners,and the heterogeneity of air-conditioning parameters is characterized by a Gaussian mixture model to accurately calculate the regulation capacity.Then,an innovative low-dimensional broadcast signal control strategy of"central guidance+local autonomy"is designed.A Markov chain model combined with an augmented Lagrangian function is used to find the optimal temperature rise probability in different temperature intervals,balancing the power grid demand and economic cost constraints.Finally,the proposed method is verified through simulation analysis.The results show that the calculation accuracy of regulation capacity reaches 97.5%in a heterogeneous sample set of 50000 air conditioners,which can stably provide a maximum load reduction of 11188.12 kW.Moreover,the broadcast strategy can dynamically track the grid demand power and effectively alleviate the summer grid peak pressure.The proposed method provides theoretical support and a practical solution for large-scale thermostatically controlled loads to participate in demand response.关键词
